A great video which is about child learning and language.
I'm always talking about this in Little Lorikeets, how important it is for babies to be exposed to English (英語). Especially when being able to recognise the sound that English makes i.e the "R" and "L" sounds, this ability is aquired when they are babies and the ability to recognise these sounds drops away they fast.
The video explains it better.
ps there is a subtitles button on the bottom bar of the video if you want :)
for those who cant see subtitles from here
